Thanks,I was cheching everything...but im a bit sick of losing time instead of playing...
So i loaded the game and played
Its a bit annoying but i can survive.
Maybe the next visibility mod can adress this problem.The night it's too dark for me,and i think im not the only one with this problem.
When the human eye get used to dark,in a good night,even without moon and only the star and in an ambient without artificial light you can see very well...i think.
I talk for experience,because i love to walk around at night in a forest(when i can,so it's mean only when im on vacation

)
I remember seeing around very well.
maybe im wrong,or maybe im some sort of vampire or werewolf
Anyway,rant off and thank everyone for the help
